Bingo !
I have tested your last two kernels, and am now running 5.12.0-5.1. Wireless is fully back again, fans aren't running anymore.
Thanks a lot for your work !

Ok I'm sorry there's still a problem: BT doesn't work, only wifi works (I hadn't tested it before).
It's not a big issue for me but nevertheless it's not fully fixed.

'BT Doesn't work' doesn't really narrow down the issue unfortunately.

If you install current git master inxi [version 3.3.04], NOT frozen distro version, then run: inxi -bEay and show that output here, that provides a good snapshot of what is going on with bluetooth, including the different levels of failure if applicable.

There's so many things that can go wrong with bluetooth that it's not possible to randomly diagnose bluetooth issues.

I suspect you don't have bluez, bluez-tools, and btusb installed. Try it again after making sure those are installed, then try:

inxi -Ea

and see it shows. If not, try the following stuff:

note that the revised inxi logic for bluetooth is fairly robust, but there are some things users have to do at times to enable bluetooth when it simply does not show but is certainly there.

Also be aware that laptops have physical bluetooth off switches, you can see if that's active by:

/usr/sbin/rfkill list

You're looking for something like bluetooth hard blocked: yes

There's another bluetooth thing that can make bluetooth not available

connmanctl enable bluetooth

I've seen at least one system with usb bluetooth where nothing showed until I ran that command.

Note that bluetooth has zero connection to your original issue.

It doesn't show.
:: Code ::
❯ /usr/sbin/rfkill list
0: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: no

:: Code ::
❯ sudo connmanctl enable bluetooth
Error bluetooth: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist


Effectively I don't have bluez-tools installed (and btusb doesn't exist), but what's strange is that bluetooth works with the stock 5.10 debian kernel, only when I reboot into your kernel it doesn't work anymore.

lsmod | grep bluetooth

I thought btusb was owned by a package, but it appears not to be, might be part of stock kernel, or part of another.

On my system, the module 'bluetooth' owns btrtl,btintel,btbcm,bnep,btusb.

It may be that you need a specific firmware, that would depend on what the device is. Not its brand name, the actual chip that runs the bluetooth.

If the device shows on 5.10 debian, that does suggest that it might be a firmware issue, maybe.

What does inxi -Jx show?

There may be a 'Device' in there that inxi was unable to determine was bluetooth but which is, that would be the device that did not load btusb.

Liquorix isn't my kernel, it's damentz's, but this issue is more in my area.

Apparently you think BT is over USB, but on my laptop it's part of the wifi card (ath11k).
I don't get it, if debian's 5.10 works it's that it finds the firmware AFAIU. and /lib/firmware is the same in any kernel. Isn't it more of a driver issue then ?

Sorry for the confusion with damentz, I'm new here :)

Oh, now I get it . those two in one wifi cards can be a real issue. Note that many or most but not all of them actually have a little usb bus to run the bluetooth part, but I've also seen in very rare but real cases bluetooth not running on the usb bus. Raspberry pi has it on a special type of serial bus, other devices may be on the pci bus, but sometimes with these 2 in one cards there are issues.

This may be enough information to let damentz determine if the issue could in fact be kernel related.

firmware-atheros may or may not help, but I don't really know about those 2 in one wifi/bluetooth devices, 'most' are wifi plus a tiny usb bus driven bluetooth, but I have never actually seen data from one so can't say.

I've seen this type of issue reported before but didn't pay attention to the details, sorry.

I can tell you a few things since I fairly recently did the bluetooth logic: your bluetooth devices is not seen as part of the pci bus, though you can check lspci to make sure. It's also not seen as part of the usb bus, which almost all consumer bluetooth devices are, in fact, I was talking to a guy into the kernel scene and he'd actually never even seen a non usb bluetooth device, but they do exist.

This issue seems to be similar: Qualcomm QCA6390 Wireless Network Adapter
The fix there is installing 'linux-firmware package. or firmware-linux which is a metapackage, ideally you'd know which firmware to install to avoid installing a whole bunch, but it's possible the firmware you needed was not included in the liquorix package.
